For example, in the expression This is not a simple division operation but rather an algebraic equation involving division. As the division is the operation of finding the quotient of the dividend by a divisor, you can reverse the division by multiplying by the quotient \( (y - 1) \): -\[ (2y + 4) = 3(y - 1) \] +\\[ (2y + 4) = 3(y - 1) \\] Next, we can expand and simplify both sides of the equation with the distributive property of multiplication over division and sibtraction. The distributive property state that for any numbers \( a \), \( b \), and \( c \), the equation \( a(b+c) = ab + ac \) holds true. The distributive property also holds true for subtraction where \( (a(b-c) = ab - ac) \) so that we can distribute \( 3(y - 1) \) over \( 3y - 3 \) to simplify the equation as -\[ 2y + 4 = 3y - 3 \] +\\[ 2y + 4 = 3y - 3 \\] Now we can isolate \( y \) by moving all terms involving \( y \) to one side of the equation and the constant terms to the other side -\[ 2y - 3y = -3 - 4 \] +\\[ 2y - 3y = -3 - 4 \\] The process of moving terms from one side of the equation to the other without breaking the equation is based on the fundamental principle of equality in algebra.
